<u>C. He participated in world-wide events, like the Panama Canal and international peace settlements.</u>
Theodore Roosevelt's term was characterized for breaking American traditional isolationist policy.
In 1904, the President enacted the Roosevelt Corollary in which America declared itself as an international police power to guarantee that Latin Americans countries met their international obligations toward European countries and in which the U.S would intervene and protect them in case that Europeans pressed their claims directly.
In 1903, Roosevelt helped Panama secede from Colombia, which later made the U.S. easier to make an agreement with Panama to begin the construction of the Panama Canal in 1904.
He also intervened in the Russo-Japanese War (1904–05) as a mediator to achieve negotiations and end the war. In 1906, he won the Nobel Prize for Peace for such accomplishment.
